AD815ARBZ-24

Instrumentation, Op Amps, Buffer Amps Overview

The AD815ARBZ-24 is a high-output current differential driver manufactured by Analog Devices Inc. It features two internal amplifiers configured for differential input/output or dual single-ended drive applications. The device supports ±15 V to ±18 V dual power supplies, delivering up to 500 mA output current with a minimum of 400 mA into a 5 Ω load. Key electrical parameters include a -3 dB bandwidth of 120 MHz, a differential slew rate of 900 V/µs, and a 0.1% settling time of 70 ns. Total harmonic distortion is specified at -66 dB under 1 MHz and 200 Ω load conditions. The component operates within an industrial temperature range of -40°C to +85°C and utilizes a 24-pin heat-enhanced SOIC package.
